Isro successfully places remote sensing satellite Resourcesat-2A in orbit


Indian Space Research Organisation, which is basking in the glory of consecutive successful launches, on Tuesday successfully placed remote sensing satellite Resourcesat-2A in the orbit.

A Polar Satellite Launch Vehicle — PSLV-C36 -carrying 1.2-tonne Resourcesat-2A lifted off from the first launch pad at Satish Dhawan Space Centre in Sriharikota, situated around 100km from Chennai, at 10.25am. Isro used an XL version of the rocket in PSLV’s 38th flight. In 18 years from 1994 to 2016, PSLV has seen 36 successful launches, placing 121 satellites including 79 from abroad.

Around eighteen minutes after lifting off from Sriharikota, PSLV-C36 placed the satellite in an 818km Polar Sun Synchonrous Orbit.

Resourcesat-2A is a remote sensing satellite intended for resource monitoring. It is a follow-on mission to Resourcesat-1 and Resourcesat-2, which were launched in 2003 and 2012 respectively.

Resourcesat-2A is expected to continue the remote sensing data services to global users provided by its previous satellites.

The satellite has three payloads which are similar to those of Resourcesat-1 and Resourcesat-2. They are high resolution Linear Imaging Self Scanner (LISS-4) camera operating in three spectral bands in the visible and near infrared region (VNIR) with a 5.8m spatial resolution.

The second payload is the medium resolution LISS-3 camera operating in three-spectral bands in VNIR and one in short wave infrared (SWIR) band with 23.5m spatial resolution.
The third payload is a coarse resolution Advanced Wide Field Sensor camera operating in three spectral bands in VNIR and one band in SWIR with 56m spatial resolution.

The satellite has two solid state recorders with a capacity of 200 gigabits each to store the images taken by its cameras, which the ground stations can later access.
